It's 12/22 and I have added relevant stuff at the end of this post. read the whole topic and look at the pictures.
-------
(Written 12/12)--This week, when we were R&R'ing the clutch, we sure felt lucky to get out the two bolts that fasten the exhaust pipe to the manifold. We put the old bolts back in because we hadn't thought far enough in advance to have new replacements for them. They sure seem like odds-on candidates to snap off next time around. So the question is: what do you think the absolute BEST replacement bolt would be for this application? Also, please include the size, length and thread for this metric-challenged guy.
THANKS!

I can't recall this one being covered, otherwise it would be a wet Shop rag...

I can't say about size, but the MFGs theory is to use soft unplated bolts so they rust in place and don't
vibrate out. (poor man's lock tite? LOL) . Ive had good luck with cad plated grade 5 bolts, 8s ive seen
snap in exhaust systems. I dont know if its from viration, Heat or a combination. Similar results with SS.

Youd think SS would be an obvious fit, but my results have been not as good as with cad pated.

You will want to double nut the dang things to insure they don't vibrate loose though.

Re: Brass nuts

Many of the better hardware stores are doing much better at stocking metric fasteners. have you tried
there? try your better ACE outlet. I'll see if OSH has them,
if you can't find them, maybe I could ship them to you.
